Deno Development Skills
Modern Deno development knowledge for AI coding assistants. These skills teach your AI assistant how to build Deno applications using current best practices.
Skills
| Skill | Description |
|---|---|
| deno-guidance | Core Deno best practices, JSR packages, CLI commands |
| deno-deploy | Deployment workflows for Deno Deploy |
| deno-frontend | Fresh framework, Preact components, Tailwind CSS |
| deno-sandbox | Safe code execution with @deno/sandbox |
| deno-project-templates | Project scaffolding templates |
| deno-expert | Code review and debugging principles |
Key Principles
These skills enforce modern Deno practices:
- JSR over deno.land/x - Always use
jsr:imports;deno.land/xis deprecated - npm: as fallback - Use
npm:packages when no JSR alternative exists - Built-in tools - Encourage
deno fmt,deno lint,deno test,deno doc - Fresh patterns - Island architecture with small, serializable-prop islands
Versioning
This project uses Semantic Versioning. When contributing changes:
When to Bump Versions
| Change Type | Version Bump | Example |
|---|---|---|
| Breaking changes | MAJOR (1.0 → 2.0) | Fundamentally altering how a skill works |
| New features, significant updates | MINOR (1.1 → 1.2) | Adding new guidance, updating documentation |
| Typo fixes, small clarifications | PATCH (1.1.0 → 1.1.1) | Fixing formatting, correcting typos |
Files to Update
When making changes, update the appropriate version numbers:
- Skill-specific changes - Update the skill's
versionin itsSKILL.mdfrontmatter - Plugin releases - Update
versionin both:.claude-plugin/plugin.json.claude-plugin/marketplace.json
For Contributors
- Include version bumps in your PRs when changing skill content
- Use conventional commits (e.g.,
feat:,fix:,docs:) to indicate change type - When in doubt, bump the MINOR version for content changes
